REPRODUCTION IN  PLANTS 
1) Reproduction :- 
   Reproduction :- is the production of new individuals 
from their parents. 
  The vegetative parts of the plant are the roots, stem and 
leaves. 
 The reproductive parts of the plant are the flowers. 
  In plants there are two main types of reproduction. They 
are asexual reproduction and sexual reproduction. 
i) Asexual reproduction :- 
   In asexual reproduction new plants without the help of 
seeds. 
ii) Sexual reproduction :- 
   In sexual reproduction new plants are produced from 
seeds.

   In sexual reproduction new plants are produced from 
seeds. 
2) Asexual reproduction :- 
     In plants there are different types of asexual 
reproduction. They are vegetative propagation, budding, 
fragmentation, spore formation etc. 
i) Vegetative propagation :- 
    In this method, new plants are produced from the 
vegetative parts like the root, stem or leaves. 
Eg :- If the stem cutting of a rose plant or money plant is 
planted in the soil we can get a new plant. 
        Potato has small buds called eyes. If a part of the 
potato with an eye is cut and planted in the soil we can get a 
new plant.  
        If a part of ginger is planted in the soil we can get a new 
plant. 
       Bryophyllum has buds in the leaf. If a part of the leaf 
with bud is planted in the soil we can get a new plant. 
       If a part of a cactus plant is planted in the soil we can 
get a new plant

ii) Budding :- Eg :- Yeast 
   In this method a small projection called bud is formed 
on the yeast cell. The bud grows and becomes a new 
yeast cell. The new yeast cell also grows and produces 
more yeast cells.
